Clean up INI handling #59
Description
- Convert 0/1 only options to bools
- Make integer options have proper constants, use those in documentation
- Make some options no longer i specific if they work everywhere (i.e. log verbose)
- Some are i specific but can be useful if connecting from LUW, identify what works in LUW to i
- Rename when applicable, can we still check for back-compat?
- Rename some confusing options (i.e. ignore user ID actually runs Db2 server job in-process)
